“We will ask all at MIT who want to participate to make their way to various points on Vassar Street and hold hands, to remember Officer Collier, and to show our support to the MIT Police and come together as a community along the route that Officer Sean Collier drove many times. I think he would have liked this,” according to an email distributed on campus Monday.
